We’ve just bought a new unregistered T6 (not yet picked it up), a 150 manual which suits us just fine. I don’t want a bi-turbo engine or DSG box, which may not be possible on the 6.1 anyway. It was a quick decision although our second Cali so knew what we were buying. The main reasons were the discount available now and the fact that the 6.1 will be more expensive with a lower discount achievable. The cost differential will therefore be very significant.
If you want one now, or at any time for that matter, speak to Liverpool. They had a Cali of the spec you want in 2 tone starlight blue and white in the showroom on Saturday (may have been sold) and have other brand new Calis in stock at extremely attractive prices.
